Most of the registers appeared to be chip revision information which is
most definitely useful to tell people about, though possibly with neater
formatting ("why is this batch of boards failing...  oh, right").  If
they're fixed device IDs then the driver should instead be verifying
that the registers contain the expected values and bombing out if they
don't.  Either way dev_dbg() isn't too helpful.
